Umm, perhaps it was being downvoted when the person commented? You know how HN works right? You know that votes fluctuate?
Further, please don't stereotype commenters here. It's not a good look. We come from all backgrounds, all with different levels of education and life experience.
HN, like any community, has multiple members, but it also has a very clear and narrow ideological uniformity (SV-style techno-libertarianism). That is why it is generally pleasant, until e.g. someone tries to challenge the common myths. This is obvious to anyone who has been outside the bubble.
